The primary purpose is to lock a fastener, like a castle nut, in position to prevent it from loosening.
The pin's legs, when bent, act as a stop, making the assembly resistant to coming apart due to vibration.
They are used to secure mechanical components or shafts in position by inserting them through a hole and bending the legs to block any further movement.
